Dublin is okay. I have never heard of Alphacentori. I have seen Early on the popularity lists on this site from the late 1800s. I always wondered if it meant the baby was early, or if it is supposed to be a variation of
Earl. Earlie (I believe this is similar to Early) was the first name of my great-grandpa on my mom's side, and the middle name of my grandpa on my mom's side.
